Don't get me wrong. The dealership has always been great. Never questioned warranty, always gave me a brand new loaner even when I was too young for a dealer car they would pay for a rental. Treat me very well. They just kind of dropped the ball the last few days about the fans and windshield. Which they are a huge dealership with a lot going on. They only have like 5 service guys that organize it all.

Got the car. Runs and sounds great! I forgot how good the engine sounds when its not covered up by a loud exhaust. Oil PSI is back to normal. The sound that I thought was a loose heat shield was A bad slave cylinder and throw out barring in the clutch which they found and replaced on their own. They even transferred over my painted valve covers for me. The guy who did the work said its a 2013 LLT. Only thing he didn't do is hook my ZL1 light harness back up to the fuze box. So my lower fogs are not powered right now. They had the car spotless inside and out and did replace the windshield and fixed the radiator fans.

Here's the million dollar question...mod or not to mod. At the least my elite catch can will go back on.

Glad to see it is all taken care of. For me, the million dollar question is if the timing chain issue still exists in your new LLT engine, or if its the same exact design as the 2010 engines.

So before this all began, did you take off the headers and everything before taking it in? I can't remember. That sounds like a lot of work lol.

So what do you guys think? What could have caused this. You two guys both know what I had before....could any of that caused my issues?

I don't think so....the LLT just has some flaws. There are good ones, and bad ones it seems, but it just seems like the engine, while having awesome tech and making great power, didn't seem fully matured if you ask me. Its sad that owning an LLT makes me nervous, as it shouldn't be that way.

An intake, headers, exhaust, and tune shouldn't force your engine to take a dump like that.

Agreed but you'd think that the engine being in the CTS for a couple years before being ported to the Camaro woulda matured it right? I dunno....I think one of these engines just came with a flaw and screwed some of us. At least GM fixed the engines

I agree. No way those mods caused the failure. I think it was an oiling issue. Either it got too low or lost pressure.
